Fatigue damage prediction of wind turbine gear transmission system considering dynamic parameter identification
摘要
Abstract
Through establishing the torsional dynamic model of wind turbine gear transmission system,a method of dynamic parameter identification and fatigue damage prediction of wind turbine gear transmission system based on mechanism model and operating state is proposed,and the dynamic response and fatigue damage prediction effect of wind turbine gear transmission system under different gear wear states are analyzed.The research results indicate that the identified gear rotational inertia and meshing stiffness are in good agreement with the target values;The contact fatigue damage of the same gear is generally greater than that of bending fatigue damage,and gear wear can exacerbate the fluctuation of dynamic meshing force and increase fatigue damage.Under different gear wear states,the estimated values of system dynamic response and gear fatigue damage are in good agreement with the target values.关键词
